B is the answer. my aunt has a malignant tumor and that means its active
Yes. Absolutely. Without heart, no one can live. It helps in pumping of oxygen rich blood to all body cells and tissues. It also helps in transportation of various materials like potassium, sodium, calcium etc. in our body. The main function is that it helps in excretion of wastes.
Since blood is liquid and heart pumps it, the waste materials like CO2, gets diffused and becomes impure blood. Then it is taken to lungs for purification and again reused.
So, heart actually helps us indirectly in many ways.

Answer:
The two types of motor neurons perform different activities: The upper motor neuron excites or inhibits the activity of the lower motor neuron, but the lower motor neuron always is excitatory because its axon connects directly to the skeletal muscle fibers. The cell bodies of motor neurons and most interneurons involved in the innervations and control of limb and trunk muscles reside in the spinal cord anterior horn and the gray matter zone between the anterior horn and the posterior horn. The neurons that innervate the head and neck are located in the motor nuclei of cranial nerves and in the reticular formation. Motor neuron axons form two types of motor pathways: The direct pathways are responsible for conscious control of skeletal muscle activity; the undirect pathways are responsible for subconscious or unconscious control.
In different tissues ie skin tissue, recovery is possible due to the cell's ability to divide constantly. new cells simply replace the dead ones and heal the injury. neurons divide very rarely, because they are highly specialized cells, so that they are not able to replace the dead. the injury is unable to recover.
The answer is abdominopelvic cavity
Abdomen is divided into four quadrants and nine regions to make diagnosis and examination of a disease easier. Every quadrants/region has a group organ that might be related to the disease. Since liver is normally located in the upper right, it will be less likely to be found on the lower right quadrant/region.
